Up and down light measurement student type biological microscope

The optical magnification is 40X~1000X. It comes with an "eyepiece micrometer" and a "stage micrometer" that can be used to convert the ratio and measure the size of microscopic objects. Built-in upper and lower light sources, it can observe transparent biological slice specimens and opaque objects. It is suitable for students' biological experiments and daily observation. Different from many entry-level microscopes, all lenses of the MR24 are made of "achromatic" grade optical glass lenses, resulting in clearer images, more vivid colors, and up to 1000X magnification. The body is made of high-strength aluminum alloy, with a strong and stable structure. With purchase, you will receive a box of slides and a cover slip each (valued at RMB 200). The MR24-UPN photography kit comes with a special mobile phone camera stand for convenient and stable recording and observation.

A good partner for science education in primary and secondary schools

MICROTECH MR24 is made of lightweight and strong aluminum alloy material, with precise and stable structure and high reliability. It is a model purchased in large quantities by many primary and secondary schools as well as liberal arts cram schools for teaching. MR24 is equipped with an "eyepiece micrometer" and a "stage micrometer" that can be used to measure the size of objects. It is suitable for educational institutions and students to purchase. The design of the hollow grip prevents the microscope from slipping and causing damage during movement, making it easy to take. The glass lens is highly durable and will not be easily damaged or stained to affect the imaging effect.

How to use eyepieces to measure the size of microorganisms "108 Curriculum Compulsory Biology for the First Year of Senior High School"

First place the engraved glass slide (stage micrometer) on the stage, and then look at the micrometer scale on the stage through the "engraving eyepiece" equipped with the MR24. Calculate the actual length of "one grid" on the eyepiece micrometer by aligning the two rows of scales. Then look at the cell slide through the marking eyepiece, calculate the number of cells occupied by the cells in the field of view, and finally multiply the "number of cells" to calculate the actual length of the "one cell" on the eyepiece micrometer, and you can get the cell actual length.

High quality stage micrometer

High-quality etching and coloring, MICROTECH double-scored glass micrometer is equipped with two different scales, suitable for both "compound microscopes" and "stereo zoom microscopes".

Achromatic optical system

Using the "achromatic optical system", the objective lens and eyepiece are composed of multiple lenses with different materials and optical properties, which can correct the dispersed light when passing through the lens and refocus it on the same point, making the image clear and sharp. The 4x, 10x, and 40x achromatic objective lenses are all fixed with steel ball positioning and rotating nose wheels. They are accurately aligned when changing magnifications and are easy to use. The 40x objective lens has a spring buffer mechanism. If the user accidentally hits the glass with the objective lens, the objective lens will automatically recoil and expand to prevent the glass from being crushed, causing danger.

The stage is stable and reliable

The slide clamp-type metal stage and focusing system are equipped with coarse adjustment and fine adjustment wheels. The durability is better than similar models. The focusing base is equipped with a limit safety device to provide an extra layer of protection to prevent the slide from being broken by collision with the objective lens. The bottom of the stage is equipped with a six-hole diaphragm, which can narrow the aperture and increase imaging contrast during high-magnification observation.

Bright and stable light source design

Using an adjustable LED light set, the light source has a long life, and the brightness and color temperature are stable, allowing you to continuously have a bright field of vision and clear images, suitable for long-term observation, and the six-hole aperture is standardized and equipped for easier operation. Equipped with upper and lower light sources, it can observe light-transmitting biological slice specimens and opaque samples (insects, minerals), making it a multi-purpose machine.

Dual power supply system, unlimited use

In addition to using the transformer connection socket for power supply, it can also be powered by three AA batteries, and its use is not subject to environmental restrictions.

Recommended additional purchase - UPN-270 mobile phone photography bracket (commonly applicable to all types of smartphones)
